I arrived about 7:30PST with Siyan. It was warm and clear with little to no wind. There was heavy dew on the grass and rice. We met Jim who said they harvested one load from Field 1 yesterday. UC Davis has pulled their equipment.

The LRG was running and the CH4 was near 3.4ppm. The cell pressure was about 119Torr, but I adjusted it back up to about 144Torr with on change in concentration.

I pulled the ground sensors and piled them around the base of the tower. When I rotated the radiation boom to the north, I broke the LRG tubing just above the T on the tower. I was able to put a new nut and farrels on it and reconnect it. In the north position the boom wasn?t very level so I tightened the counter balance cable to bring it into a more level position.

The CR1000 was not connecting in logger net. Reconnecting the USB adapter didn?t fix it. Restarting Loggernet did. All looked okay.

I picked up another LI7500 from Frank for Calibration.
